If you have the forward pattern valve body it may use the direct clutch restrictor plug in the case.
From the instructions on Copes web page, the reverse pattern shifters do not use a restrictor plug.
Here is what is posted at

Install all 15 springs into the front drum. If your piston only has 10 springs, CRT offers the 15 spring pistons and new springs. Use the late 1.40 springs only.
Stock clutches will work. Alto red racing clutches work better. Set front clutch at .070 - 0.79 .
Band adjustment = front band 72 inch lbs back off 2 turns. Rear band 72 inch lbs back off 2&1/4 turns.
Lever ratios = 3.2 & 3.8 works good. 4.2 with 62-70 front servo and 2 springs works best. Never use the 5.0 lever with this valve body. Heavy duty band strut will prevent strut from bending.
If your case has a orifice restrictor ( common with TF-2 shift kits ) remove it.
You can use a stock dacron ( works best) or a brass high flow filter.
CRT has found that ATF+3 transmission fluid works the best.
Made by Mopar or Pennsoil Dextron II or III work well also
Shim rear servo, or install the billet servo kit.
Shim front servo 71 & later, or install 62-70 billet servo kit.
Install teflon sealing rings on pump stator .Never do 1st gear burn outs in water box. Always use SFI shield / blanket. For your safty, its best to install a front billet drum.
